CONTRACT SPIN-OFFS

The Directors of the IEM reserve the right to introduce new
contracts to the market as spin-offs of existing contracts.
When a contract spin-off occurs, an original contract will
be replaced by two or more new contracts which subdivide the payoff
space of the original contract. No holder of the pre-spinoff
contracts will be adversely affected. Traders will receive
the same number of each of the new contracts as they held
in the original, and the sum of the liquidation values
of the new contracts will equal the liquidation value of
the original.

Only the contracts NYRep, NYDem, NYInd, can be spun off.

>
Decisions to spin-off a contract will
be announced at least two days in advance of the spin-off.
The new contract names, the specifications regarding liquidation
values and the timing of the spin-off will be included
in the announcement. This announcement will appear as
an Announcement on your WebEx login screen.
